Approach: Quartz-carriers [...] from the contaminated sample is unaccounted for, possibly due to a different count of photons from the X-Ray tube and the relatively low Hg concentration. Cross-contamination is to be expected if samples [...] Storage at low temperatures is favorable to avoid Hg loss. In addition, the time between sampling and sample measurement should be limited. Individual storage of samples is advisable to avoid cross-co
